GAS-BURNER.

SPECIFICATION forming part of Letters'latent No. 729,470, dated May 26, 1903.

Applicata filed Augustl 9, 1902.

Be it known that I, CHARLES T. watson, a

citizen of the United States, residing at Ame-V nia, in the county of Dutchessv and State ot'v .New York, have ninvented certain new and useful Improvements in Gas-Burners; and I do declare the followingr to be a full, clear, andl eXact description of the inve,ntion,such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to devices for automatically turning on and oi a gas-lournerand4r igniting the gas.

The object is to provide a-device of this 1 character which can be applied to any gas-K txture in place of theordinary burner and which will be automatically operated and controlled by the pressure of the gas-within theY pipes, another object being to provide a de-f vice of this character by which the lightsof burners equipped with this formy of burner may be ignited or extinguished Without interfering in any manner with other lights-ofrordinary burners in the same line of piping. A further object is'to provide such a device which will be simple in construction, durable in.use,ineXpensive to produce,and well adapted to the use for which it is designed.

With these and other objects in viev. the invention consists in the construction and ar-' rangement of the parts, as will be hereinafter more fully described and claimed, reference being had to the accompanying drawings, in-l Which- Figure 1 is a longitudinal vertical section of the device. Fig. 2 is a top plan view of the same, and Fig. 3 is a longitudinal v erticalsect-ion of a modified form of the device."

In the drawings, referring particularly to Figs. 1 Vand 2, the numeral 1 denotes the bodyV or base of the burner, consisting of a shallow cup, preferably cylindrical in shape, the vertical sides of which are provided with an annular ange 2 and the bottom 3 of which is formed with a centrally-disposed depending nipple 4, having interior screw-threads and is adapted to be attached to the bracket or gas-Iixture of a gas-service pipe.

5 denotes a ring corresponding in diameter and shape to the ange 2, the said ring and iiange being provided with alined screwsmihra11a115.` uro model y threaded holes to receive screws 6, Awhereby they are'clam'ped together.

7 denotes an arm or bracket rigidly con- 4 nected to or formed integral with the ring 5, the upper -end of the bracket or arm being arranged in a horizontal plane above the body 1. .Y y Y A 8 denotes a burner-pipe supported .upon the arm 7 and having formed near its lower 6o end a valve 9,to the stem of which is con, nected an operating-lever 10 and an upwardlyprojecting arm 12. Upon the upper end of the pipe 8 is attached atburner or tip 13, provided with a contact-piece forming one term-inalof one Wire 14: of an electric circuit,. the other wire 15 ofthe circuit being connectedfto the stem of valve 9, the arm 12 of which has on its opposite end a wire contacttingerl, forming the opposite terminal of 7o the electric circuit. The wires 14 and 15 of the said circuitlead to a suitable source of electricv supply and sparkingdevice. (Not shown.)V

17 denotes a diaphragmiormed of a thin 75 sheet Vof flexible material which is adapted to be placedupon' the flange 2 and to be clamped theretoI by thejring 5, thus forming a gastight top for the cup 1. Upon the diaphragm .17 is adapted to be placed a disk 18, of any 8o suitable size and material and of proper 'v1/eight.

y 19V denotes a rod or link pivotally connectedat one end tothe disk 18 and at its opposite end to the lever`10, by which means the valve is rocked. The disk 18 may be attached to the diaphragm in any suitable manner, but preferablyby means of a small screw 20 passing 'upwardly through the diaphragm and intothe disk.

21 denotes a burner feed-pipe communicating at its lower end with the cup 1 through the side thereof'and communicating at its upper end with the burner-pipe below the va'lve 9.

In Fig. 3 of the drawings 'Iv have illustrated 95 a modified construction of the device. In this instance I do away with the valve in the burner-pipe, and in the bottom of the cup 1 I place a nipple 22, and in the lower end of the burner-pipe I place a similar nipple 23, loo each nipple being formed on its end with a head,to which are connected the opposite ends of a flexible pipe 24. The nipple 22 is adapted to project above the bottom 3 of the cup a slight distance and forms a seat for a valve 25, consisting of a thin disk of suitable material fixed on the end of a Hat leaf-spring 26. The lower side of the'disk 25 is provided with a Washer 27, of leather or other soft material, which will tightly engage the seat on the end ofthe pipe 24 when pressed against the same.

The closing of the valve 25 is caused by the falling of the diaphragm and the disk 18, due to a reduction of gas-pressure in the pipes and cup l. The diaphragm in falling engages the valve 25, forces the same down on its seat against the tension of the spring 26. When the force of gas is again increased, the diaphragm will be raised and the valve released, and which by action of the spring will be lifted from its seat and again permit gas to flow to the burner pipe and tip, where it will be ignited in the same manner as described in Fig. l.

In operation, the disk 18 being of such weight that it will remain supported by the diaphragm while the gas is at a certain pressure and the valve will remain closed, as soon as the pressure of gas is increased the diaphragm and disk will be raised, thereby rock-- ing the valve 9 to turn on the gas and simultaneously moving the arm 12 and the [inger 16 into contact with the opposite terminal on the burner-tip to cause a spark whereby the gas is ignited, and upon a decrease of gas below a certain pressure the diaphragm and disk will fall, and thereby reverse the movement of the lever 10 to turn olf the gas.

The parts might be adapted for a reverse operationthat is, so that a reduction in presresorted to without departing from the prin-- ciple or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described, the combination with a gas-burner; of a cup having a gas-inlet thereto, a diaphragm actuated by the gas within the cup, a pipe establishing communication between the burner and cup, a cut-oli valve to control the supply of gas to the burner, a connection between the cut-off valve and the diaphragm, and an electric igniting device including a movable electrode actuated by the movement of the diaphragm, substantially as described.

2. In a device of the character described, the combination with a gas-burner; of a cup having a gas-inlet thereto, a diaphragm actuated by the gas within the cup, a pipe establishing communication betwcen the cup and the gas-burner, a cut-ot valve carried by the gas-burner and provided with a crank-arm, a link pivotally connecting the crank-arm with the diaphragm, an electric circuit, and an igniting device including a. movable electrode connected to the valve and operated simultaneously therewith, substantially as and for the purpose set forth.

3. In a device of the class described, the combination of a gas receiver having a weighted diaphragm movable in one direction by gas-pressure in the receiver, a burner, a gas-conductor connecting the same with the receiver, a valve to control the supply of gas to the burner, and a rocking electric igniting device connected to the diaphragm and also connected to the valve, whereby said device and valve are simultaneously operated by the diaphragm, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
